Broken Capacitor. Please help me identify it for replacement.

Looking to get an ID on this missing capacitor. It's located near the FireWire port opposite the heat sink/gpu side of the logic board.

Update (03/29/2017)

Reference number for the board is 820- 2879

@gyagre92 that is L4310 which is a 250 Ohm Ferrite Bead. To determine which package size it is you will have to measure from contact to contact and compare it to the attached chart.

Thanks. I updated the questions with more information and better photos.


@gyagre92 probably an 0603 or 0805, would recommend measuring it since they don't say in the schematic.

This component is exclusively for firewire port functionality, if you have any issue other than the firewire port not working, this will not resolve your issue.
